Sorry I didn't warn you about that man. It is a factory safety check of all the circuits and all DB750's do it. Check the Aguilar website and you'll find it listed as a feature with the amp description. I hope your enjoying that amp

As good as that is for the health of the amp it worries me on a gig... My surge protector got unplugged at rehearsal in the middle of a song and I couldn't get back on for 45 seconds. I better tape the plug to the wall socket!
